An investigation of the genetic and meristic patterns of coastal cutthroat trout
(Oncorhynchus clarki clarki) in two coastal basins, one in Oregon and one in Alaska,
revealed varying degrees of differences among popula ...

The heritability of resistance to death from the effects of lead in laboratory guppy populations was determined from comparisons between progeny produced in a nested breeding experiment and from
mass selection experimen ...

The contribution of genetic effects to the variation in percent normal development observed in a bay mussel (Mytilus edulis L.) embryo bioassay was determined. A factorial breeding experiment
was accomplished in which 9 ...

Understanding local and geographic factors influencing species distributions is a prerequisite for conservation
planning. Our objective in this study was to model local and geographic variability in elevations occupied ...

The spatial ecology of a species is a vital component of informed management and restoration plans, yet little is known about how animals use restored or constructed habitat. We assessed home ranges, core areas, and habi ...

Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored ...

Greater sage-grouse (Centrocercus urophasianus) populations declined range wide
during the past 50 years. Grouse populations were 2-3 times larger than the current
population as recently as the early 1970's. In additio ...
